Germany’s Roman Catholic bishops sacked a criminologist studying sexual abuse of minors by their priests on Wednesday, prompting him to accuse them of trying to censor what was to be a major report on the scandals.

The independent study, examining church files sometimes dating back to 1945, was meant to shed light on undiscovered cases of abuse after about 600 people filed claims against molesting priests in 2010 following a wave of revelations there.

The German scandals were part of a series of abuse scandals that also shook the Catholic Church in Ireland, Belgium and the Netherlands and forced Pope Benedict to issue a public apology.

Bishop Stephan Ackermann, spokesman on abuse issues for the German Bishops Conference, said the hierarchy had lost confidence in the researcher, criminologist Christian Pfeiffer, and would look for another specialist to take up the study.
